Walking Together | Baiweide and Dr. Yang Haiming, PhD in Agricultural Chemistry from Taiwan University, Achieve Strategic Cooperation

On April 4, 2023, Dr. Yang Haiming, Ph.D. in Agricultural Chemistry from Taiwan University and General Manager of Taiwan Xiuming Technology Co., Ltd., visited the Natural Land Group for exchange and visit. Yang Haiming is a Ph.D. from the Institute of Agricultural Chemistry at National Taiwan University and an expert in pest and disease prevention. Deeply cultivate multiple fields such as disease and pest prevention and control, cut flower preservation technology, and biotechnology. Both sides conducted in-depth discussions on the development and cooperation of Baiweide in the field of chitosan oligosaccharides.

What is chitosan oligosaccharide?

Chitooligosaccharides, as an exogenous biological inducer that has been extensively studied in recent years, have been applied in the production of various crops such as grapes, strawberries, tobacco, chives, wheat, rapeseed, strawberries, cucumbers, citrus, etc. They have great potential in regulating plant growth, development, reproduction, disease prevention, and disease resistance.

Chitooligosaccharide is a product obtained through partial hydrolysis of chitosan, consisting of 2-10 N-acetylglucosamine or glucosamine molecules β- Oligosaccharides formed by linking 1,4-glycosidic bonds have advantages such as low viscosity, good water solubility, and easy absorption by living organisms, therefore they have more biological activity and physiological functions than chitosan.

Working principle of chitosan oligosaccharides

Chitooligosaccharides (plant vaccines) not only induce plant disease resistance and participate in plant defense responses, but also induce plant stress resistance (cold resistance, drought resistance, and waterlogging resistance), promote plant growth and yield increase, improve crop quality, reduce pesticide residues, and extend crop storage limits, among other functions.

The role of chitosan oligosaccharides in crops

1. It can increase beneficial microorganisms such as actinomycetes in the soil and reduce harmful bacteria such as Fusarium.

2. Eliminate root knot nematodes and feed the soil for continuous cropping obstacles. Effective in preventing and controlling soil borne diseases such as tomato gray mold, citrus bacterial ulcer, cucumber downy mildew, and mango anthracnose.

3. Causing soil to form agglomerates, improving soil aeration, drainage, and fertility, thereby promoting root development, increasing root hair, enhancing nutrient absorption, promoting plant growth, and increasing yield.

4. Inducing the elevation of plant phytoprotectants and reducing the occurrence of viruses. Activate the activity of chitinase in plants, enhance crop disease resistance and antibacterial activity, and reduce pesticide use. The prevention and control rate of rice blast disease is as high as 50%. The control effect on sheath blight is over 65%.

5. Inducing the production of phytotoxins in plants, improving crop disease resistance and antibacterial activity, in order to reduce pesticide use.

6. Increasing the calcium content of vegetables and fruits can increase crop brittleness, reduce bitterness, and improve taste.

7. Enhance the absorption of trace elements to increase crop sugar content, harvest early, improve quality, and extend shelf life.

During the visit, Zhang Guangyou, Chairman of Nature Group, and Dr. Yang Haiming held strategic cooperation talks and reached a consensus on cooperation. Both sides have high hopes for future cooperation. We also believe that under the guidance and technical support of Dr. Yang Haiming, Baiweide's technological application and product quality in the field of chitosan oligosaccharides will undergo gratifying changes, achieving a qualitative leap.
